Amazon offers Prime members Intuit TurboTax 2015 Deluxe Federal + Federal eFile + State Tax Preparation Software for Windows and Mac, bundled with a download of Kaspersky Anti-Virus 2016 1-User for Windows for $42.49 with free shipping. (Non-members can spend $49 or more to qualify for free shipping; otherwise, shipping costs $4.48.) That's $13 under the lowest total price we could find for these items purchased separately elsewhere. (For further comparison, we saw the tax software alone for $40 shipped in January.)
